BonOs® Inject is a radiopaque, injectable bone cement for the treatment of pathological fractures of the vertebral body due to osteoporosis, cancer, or benign lesions using vertebroplasty or balloon kyphoplasty procedure. When used in conjunction with NEO Pedicle Screw System™ BonOs® Inject is intended to restore the integrity of the spinal column even in the absence of fusion for a limited time in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion. NEO Pedicle Screws augmented with BonOs® Inject Cement are for use at spinal levels where the structural integrity of the spine is not severely compromised. Mixing the two separate sterile components initially produces a ductile, injectable bone cement which, after hardening in situ, is able to stabilize neoplastic vertebral lesions and vertebral compression fractures. BonOs® Inject cement powder also contains insoluble zirconium dioxide as an X-ray contrast medium.
A non-bioabsorbable, implantable device made of a synthetic material(s) intended to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis); it is not dedicated to dental applications and is not intended for implant fixation (not a bone cement). It may be a powder [e.g., polymethylmethacrylate (PMMA)], or a non-PMMA-containing elastomer formed by mixing two precursors, prior to implantation typically during a balloon kyphoplasty or vertebroplasty procedure; it does not include an antimicrobial agent(s). It may also be referred to as a bone augmentation material.
